Water flows in harvestable areas for Antarctic krill (Euphausia superba) on the continental slope and shelf of the South Shetland Islands were examined based on drifting buoy data. Convergent complex eddies were observed in harvestable areas on the shelf, while shear current was observed in those on the slope. Large-scale movements of the buoys suggest krill flux from the South Shetlands into South Georgia or the South Orkneys.
